Using these mini building blocks is easy! First, take out the pieces from the reusable storage container. Then, refer to the instructions to start assembling the gorilla character piece by piece. It might take a little patience, but the end result is really rewarding. When you're done building, you can either display your gorilla or put it back in the storage container for safekeeping. As for maintenance, just keep the blocks in a dry place to prevent any damage. And if you want to clean them, you can use a soft, dry cloth. Remember, these blocks are suitable for all ages, so have fun building and collecting!
